Crepovići / Цреповићи) was among the most notable Serb noble families in the mid-16th century in Hungary, with their head, Nikola Crepović (Serbian Cyrillic: Никола Цреповић; Hungarian: Cserepovics Miklós; Turkish: Cerepoviki).

In 1550, he was a colonel in the army of Petar Petrović, a relative of Zápolya, who was in armed conflict with fra Juraj Utješenović-Martinušević, a Dalmatian monk and later bishop of Nagyvárad, and the Cardinal, the main individuals of Zápolya's court.

In the battle around Csanad against fra Juraj, some 6,500 Serbs and Turks were captured, while Crepović managed to save himself, the cities which he had taken were returned.

In 1551, he was among Ferdinand's voivodes that received a mercenary salary; at the end of that year he was in the army of fra Juraj, while in December he was at the top of the defence of Timișoara when the Ottomans attacked, and managed to capture him, though he was later released from prison.

King John Sigismund Zápolya (r. 1540–70) adopted Jelena as a sister, and guested the wedding, but she later divorced and married Vladimir the Moscovian.
